2 Claims.

The invention relates to hinge mountings and more especially toconcealed hinge constructions.

The primary object of the invention is the provision of a hinge, whereinthe same is adaptable for the mounting of doors on automobile bodies sothat said door can be swung from closed to open position or vice versairrespective of the curved contour of the body of the automobile and thehinge concealed from view when the door is closed.

Another object of the invention is the provision of a construction ofthis character, which is comparatively simple in its make-up, thoroughlyreliable and ecient in operation, strong, durable, readily and easilyplaced in working position in a door frame and door, assuring the easyswinging of the door without sagging of the latter and inexpensive tomanufacture and install.

With these and other objects in view, the invention consists in thefeatures of construction,

combination and arrangement of parts as will be hereinafter more fullydescribed, illustrated in the accompanying drawings, which disclose thepreferred embodiment of the invention and pointed out in the claimshereunto appended.

In the accompanying drawings:

Figure 1 is a fragmentary vertical sectional view through a doorway of amotor vehicle body showing the door open and supported upon hingesconstructed in accordance with the invention.

40 view showing a double hinge arrangement.

Figure 7 is a vertical sectional view through one part of the singlehinge.

Figure '7A is a plan view thereof.

Figure '7B is a` plan View of another part of 45 the single hinge.

Figure 7C is a sectional view thereof.

Figure 8 is a plan View of another part of the single hinge.

Figure 8A is an edge elevation thereof.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, A designates generally a portion ofthe body of a motor 55 vehicle and. the same having built therein aApplication January 3, 1936, Serial No. 57,435 i y doorway B for aswinging door C, the doorway and the said door being curved at the lowerportion thereof as is customary or usual and for the close and propertting of this door in the doorway there is employed the upper, lower andintermediate hinge mountings constituting the present invention and thesaid upper and intermediate mountings, each includes a pair of guideplates Ill which are 'superimposed one upon the other and are of a shapeto match each other while built with these plates are securing iiangesII accommodating fasteners I2 which stationarily fasten the said platesin matched superimposed relation to each other within the door frame Bat the hinge side thereof. These plates at their meeting faces areformed with arcuate guide ways I3 which register with each other andaccommodate an arcuate bearing I4 of a swinging part I5 for an attachingear I6 for the fastening by fasteners Il of this part to the door C sothat said door will be hung by such part I5 and hinged for opening andclosing movements. The plates I0 are detachably fastened in superimposedrelation to each other by suitable fasteners I8 and the bearing I4interts the guide ways I3 the part I5 on the swinging of the door C cannot separate from between the plates IIJ and free swinging action of thedoor C is had.

The lower hinge for the door C includes the pair of plates I9 for thematched arcuate groove or guide way 2i) for accommodating the arcuatebearing ZI of the hinge part 22, this arcuate bearing being providedwith an arcuate slot 23 accommodating a stop pin 24 as fitted within theplates I9, these plates being mounted in place by the fasteners. 25 andare joined with each other by fasteners 26. The part 22 has theattaching ear 2l to which is fastened fasteners 28 for securing it tothe door C. The bearing 2| is of a considerable greater arc than thebearing I4 due to the curvature of the door frame B and the door C atthe lower portions thereof where the lower hinge is fitted.

In Figure 6 of the drawings there is shown the employment of a doublehinge which includes the plates 29 which are provided with the gui-deways 30 for the bearings 3l of double swinging parts 3L so as to effecta double hinge arrangement as will appear from Figure 6 of the drawings.Each part 32 is similar to the part I5 hereinbefore described and theplates 29 of each pair are similar to the plates IIJ.

It will b-e apparent that the hinge arrangement or mounting eii'ectsconcealment of the hinges for the door C when the latter is closed.

The stop pin 24 limits the swinging action of the door C when moved toopen position and also eliminates the separation of the bearing 2| frombetween the vplates I 9 and such bearing freely slides in the guide ways20 in the said plate.

The plates l0, I9 and 29 are suitably cut away as at 33 to accommodatethe parts l5, 22 and 32 When'the door C is closed for the close andtight fitting of the said door in the door frame B.

What is claimed is:

1. A hinge of the character` described comprise ing a stationary memberformed of apair of contacting superposed plates having matched arcuateshaped guide ways provided in their meeting faces, an arcuate shapedswinging member slidably tting in said guide ways, and iianges at theouter sides of said members for fastening of the latter in place on a.door frame and door respectively.

2. A hinge of the character described comprisl ing a stationary memberformed of a pair of superposed plates having matched arcuate shapedguide ways provided in their meeting faces, an arcuate shaped swingingmember slidably fitting in said guide ways, a'nges at the outer sides ofsaid members for fastening of the latter in place on a door frame anddoor respectively and means separably joining the plates together incontacting superimposed relation to each other.
